Item Type: Surge Protection Device <br>Color: White <br>Material: PC <br>Maximum Discharge Current: 60KA <br>Nominal Discharge Current: 30KA <br>Protection Level: 2.0KV <br>Shielding Grade: IP20 <br>Response Time: ≤25ns <br>Maximum Wire Diameter: 35 hard wire or multi strand wire(mm2) <br>Recommended Wire Connections: 4-25(mm2) <br>Installation Method: 35mm electrical rail mounting <br>Ambient Temperature: -40℃ to +80℃ <br>Main Structure and Operating Principle: <br>In the three phase four wire system, three phase lines and a neutral wire to ground are connected between the protector. Under normal circumstances, the protector is in a high resistance state, when the power grid due to thunder or other reasons out of the reason surge overvoltage, the protector will be immediately in the nanosecond time quickly conductive, the voltage overvoltage into the earth, thus protecting the power equipment on the grid. When the surge voltage through the protector, and disappears after the protector revert to a high resistance state, so as not to affect the normal operation of the grid.<br>1、Device Working Mechanism: When the system has a surge overvoltage due to thunder or other reasons, the protector immediately opens quickly within nanoseconds and introduces the surge overvoltage to the earth to provide protection for electrical devices. <br>2、Insulated Terminal: This surge protection device is with plug in design, support hot line operation. Insulated terminals, reliable and safe, rapid response time, strong load bearing capacity. <br>3、Condition Indication Window: This surge protection device has a working status indication window, green indicates normal, red indicates fault. <br>4、Fireproof and Corrosion Proof: Our surge protection device is fireproof and corrosion resisting and stable, can effectively respond to the working status. <br>5、Made of PC Material: Our surge protection device is made of flame retardant PC material with exquisite craftsmanship, easy to use, very simple to install through the guide rails.1 x Surge&nbsp;Protection&nbsp;Device
